Case Study:Kcoffee

 

LBO Model Test Instructions

A private equity firm is considering the leveraged buyout of , KCoffee a privately-owned coffee company. In the last twelve months (“LTM”), KCoffee generated $2bn in revenue and $150 mm in EBITDA. If acquired, the PE firm believes Kcoffee’s revenue can continue to grow 15% YoY while its EBITDA margin remains constant.

To fund this transaction, the PE firm was able to obtain 4.0x EBITDA in Term Loan B (“TLB”) financing – which will come with a seven-year maturity, 5% mandatory amortization, and priced at LIBOR + 500 with a 2% floor. Packaged alongside the TLB is a $50mm revolving credit facility (“revolver”) priced at LIBOR + 500 with an unused commitment fee of 0.25%. For the last debt instrument used, the PE firm raised 2.0x in Senior Notes that carries a seven-year maturity and an 8.5% coupon rate. The financing fees were 2% for each tranche while the total transaction fees incurred were $15 mm.

On KCoffee’s balance sheet, there is $300mm of existing debt and $50mm in cash, of which $30mm is considered excess cash. The business will be delivered to the buyer on a “cash-free, debt-free basis”, which means the seller is responsible for extinguishing the debt and keeps all the excess cash. The remaining $20mm in cash will come over in the sale, as this is cash that the parties determined is required to keep the business operating smoothly.

Assume for each year that KCoffee’s depreciation & amortization expense (“D&A”) will be 5% of revenue, capital expenditures (“Capex”) requirement will be 2% of revenue, the change in net working capital (“NWC”) will be 1% of revenue, and the tax rate will be 35%.

If the PE firm were to purchase KCoffee at 10.0x LTM EV/EBITDA on 12/31/2021 and then exit at the exact LTM multiple after a five-year time horizon, what would the implied IRR and cash-on-cash return of the investment be?

Geographic expression or expectation of gender

 

 

Using the Internet and the Online Library, review a variety of media characters, analyzing how male and female characters are portrayed. Media can be videos, cartoons, comic books, movies, etc. What are some common themes and characteristics in these portrayals? What messages do these send to young children about gender roles? Critically evaluate the scientific evidence for gender differences in a variety of areas such as social roles, cognitive abilities, education, self-esteem, and self-confidence.

In addition, address the following:

Emotional expression of gender: How did the social cultural aspects of media, observational learning, and other factors influence your perception of gender-appropriate emotional expression?
Social expression or expectation of gender: Is there a difference between genders in terms of expression of responsiveness to babies or nurturance? Do we encourage little boys to express feelings aggressively and little girls to articulate and verbalize their emotions?
Geographic expression or expectation of gender: Are there differences within or across various cultures and geographical areas?

People Centered

 

In many organizations, being people-centered is considered soft, irrelevant, and unrelated to profitability. Based on the video, “Everybody Matters: A Documentary Short Based on the Best Selling Book” and the assigned readings on conscious capitalism, contemplate the conscious capitalism principles (e.g., conscious leadership, stakeholder orientation, conscious culture, and higher purpose) as a framework. Consider at least two companies that successfully adopted this business philosophy to gain success and combat traditional corporate approaches. How do these companies embody the tenet of “higher purpose” and create deeper meaning by focusing their goals beyond profits and inspiring stakeholders? What connections can you identify between the four principles of conscious capitalism and the Christian concept of putting others before oneself?
